Summary of the contracting process

Dundee City Council is procuring a multi-supplier framework for building surveying, timber preservation and related remedial services in domestic properties in Dundee. The work covers surveys and treatment for dry rot, wet rot, woodworm infestation and chemical mould removal. It is divided into three lots: surface treatments for condensation, dampness and mould excluding fogging; invasive treatments and investigation; and mould-treatment fogging. Services may include damp proofing, timber preservation, fungal decay treatment, basement waterproofing, building inspections, remedial works, mould remediation, antimicrobial treatment and associated certification and reporting. The council intends to appoint between three and five competent contractors to each lot, and organisations may bid for all three lots.

The procurement has reached tender: the council invited offers through an open procedure for a framework agreement. The tender closing deadline and bid-opening time are 5 October 2026 at 12:00, with evaluation scheduled to start at that time. Each lot has a 720-day contract period and may be renewed for two further one-year periods. The estimated total value is £5.2 million. The framework may include up to 15 suppliers. Bids must be in English, remain valid for 120 days and cannot include variants. Each lot is awarded to its highest-scoring bidder, using price weighted at 60% and quality at 40%. Quality includes service delivery, resourcing, communication, customer care, continuous improvement, community benefits, Fair Work First, compliance, health and safety, cyber security, environmental performance, sample reports and 24-hour response capability.

This opportunity suits building, joinery, property-preservation, mould-remediation and environmental-treatment contractors with the resources to deliver complete works and respond within 24 hours. Lot 1 is suitable for competent general building or joinery businesses, provided they can demonstrate relevant competence, experience and resources; specialist regulated work can be carried out by appropriately qualified employees or subcontractors. Lot 2 requires specialist expertise in damp proofing, timber preservation, fungal decay, wood-boring insects, basement waterproofing and associated remedial work. The principal contractor must hold current Property Care Association membership, employ qualified surveyors and technicians, and provide surveys, recommendations, guarantees and completion certification. Lot 3 requires proven mould-remediation experience, fogging, HEPA filtration and moisture-assessment capability, trained operatives and current Property Care Association or approved equivalent membership. All bidders need suitable financial strength, including an Equifax score of at least 35, and must deliver 14 community-benefit outcomes.
